METHOD OF MAKING CUFF-BUTTONS.

To all whom it may concern."

Be it known that I, MEYER L. Ronnms, a citizen of the United States, anda resident borough of Manhattan, inthe county of Improvements in Methodsof Making Cudwhich the following is a specification.

This invention relates to certain new and useful improvements in makingcufi. buttons and particularly to making cufl" buttons of a kindcommonly known and referred to as link buttons. v

The object of my invention is to produce by a new and improved method alink button composed of a single continuous integral further to makesuch Integral buttons fro a blank strip of solid metal having a web andan accumulation of metal of greater thickness than the web along eachlongitudinal edge, by which new and improved method. such buttons ofperfect shape, form and construction can be made entirely by machineryvery rapidly and economically without seam or soldered piece of metaland joint.

' illustrated one In the accompanying drawings 1 have way of carryingout my new and improved method and in these drawings Figure 1 isaperspective view of the flanged or substantially I beam shaped blankstrip from which the individual buttons are to be made. .Fig. 2 showsthe same blank somewhat changed in dimensions of its various componentparts. Fig. 3 is a perspective View of one of the individual blanks cutfrom the blank strip. Fig. 4 is a similar view of the same with theaccumulations of metal at the two ends compressed and broughtinto a moreor less bulbous shape adapted for forming certain parts of the button.Fig. 5 is a side elevation of the individual blank after it has beensubjected to dies for shaping it and whereby a central longitudinalplane fin is formed around .the individual blank. Fig. .6 is an edgeview of this blank and fin. Fig. 7 is anelevation of the individualblank after the fin has been out 011'. Fig. 8 is an edge View of thesame. Fig. 9 is a perspective view of the invidual blank after. thebottom bulb has been pressed into disk shape and the surplus metalappears as a fin around the base or disk. Fig. 10 is a similar view ofthe same after the fin surrounding the base has been specification ofLetters'fPetent. Application filed February w, 1915. Serial No. 9,2fi5.

- In the drawings 15 represents a blank strip from which the buttons areto be formed, said strip preferably consistingof as gold or silver andthis blank strip 15 has a cross section composed of a web 19 and anaccumulation of metal along each edge of the web as' shown at 17 and 18so that this blank strip has sub- Fig. 11 is aside Patented net. 5,rare.

stantially the shape in cross section of an 1- I sisting of a stem 22which has been formed out of the web 19 of the original blank strip 15and this stem 22 has an accumulation 20 of metal at its upper end and anaccumulation 21 of metal at its lower end, the upper accumulation orhead 20 being v formed or cut out of the top flange 17 of the blankstrip 15'and the lower accumulation of metal or base 21 being cut orformed out of the bottom flange 18 of the original blank strip 15. Thisindividual blank is then subjected to pressure between suitable dies soas to compress the head20 into approximately a ball or bean shape asshown at 23 in Fig. 4 and thebase 21 into a ball or bulb shape as shownat 24 in Fig. 4'. The individual blank thus obtained. and illustrated inFig.4 is then placed into a press and by means of suitable dies insaidpress-this blank is compressed to form the two opposite sides of thestem 22, substantially semi-circular as shown at 27 in Figs. 5 and 6 andto round the con- .tours of the head 23 so as to bring it into a socalled bean shape as shown at 25 in Figs. 5 and 6. At the same time thebase 24 of Fig. 4 is converted into an approximately oval or ellipticalbase portion 28 rounded at the top,

ing the metal between dies as aforesaid the bottom and side surfaces. Bypress-
